Description

Technical Field

[0001] The utility model relates to the technical field of ore, in particular to an ore crusher. Background Art

[0002] To put it simply, ore is a stone containing minerals. Specifically, ore is a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. According to classification, ores can be divided into two categories, namely metallic minerals and non-metallic minerals.

[0003] After the ore is mined, it needs to be crushed so that the raw materials meet different particle size and shape requirements, so as to provide materials of suitable particle size and shape for subsequent mineral processing operations. This can not only improve the utilization rate of the ore, but also ensure the mineral processing effect. Secondly, the crushed ore can better adapt to the working principle of the grinding equipment, thereby improving production efficiency. At the same time, the crushed ore has a smaller particle size and a more regular shape, which is conducive to improving the transportation efficiency of the ore and reducing the demand for storage space.

[0004] In the prior art, when the ore is crushed, since the ores are originally of different sizes, it is easy for the size difference between different ores to remain large after a single crushing of the ore. Excessive size difference will have an adverse effect on subsequent ore processing. Therefore, an ore crusher is proposed to solve the above problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an ore crusher, the purpose of which is to solve the above problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Two crushing rollers are installed inside the crushing box, and two slides are installed below the crushing rollers. The slides are fixedly connected to the inside of the crushing box, and a crushing mechanism is installed inside the slides. The lower end of the crushing box is fixedly connected to a row plate. The crushing mechanism also includes an extrusion assembly installed inside the slide, and a crushing roller is installed on the outside of the extrusion assembly. The crushing roller is rotatably connected to the inside of the crushing box. A second motor is installed below the first motor, and the second motor is installed at the outer end of the crushing box. The output shaft of the second motor is connected to the crushing roller. The extrusion assembly also includes a mounting frame slidably connected to the inside of the slide, and the side of the mounting frame close to the crushing roller is rotatably connected. A hydraulic telescopic rod is installed on the side of the inside of the slide away from the squeezing roller, and the hydraulic telescopic rod is fixedly connected to the crushing roller, and the output end of the hydraulic telescopic rod is fixedly connected to the mounting frame.

[0009] Preferably, a discharge hole is provided at the lower end of the crushing box, and the discharge hole is connected to the row plate.

[0010] Preferably, a first motor is installed at the outer end of the pulverizing box, and an output shaft of the first motor is connected to the pulverizing roller.

[0012] Preferably, belts are wound around the outer sides of the two transmission blocks, and the belts are in an 8-shaped structure.

[0013] Preferably, the crushing roller and the squeezing roller are at the same horizontal position.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides an ore crusher, which is provided with a crushing roller and a crushing mechanism, and can perform two crushing processes on the ore to reduce the size difference of the ore after the crushing process. After starting the first motor, a crushing roller can be driven to rotate, and the rotation is transmitted through the belt, so that the two crushing rollers can rotate towards each other to perform the first crushing on the ore.

[0023] like Figure 1 A mineral crusher comprises a crushing box 1, the bottom of which is fixed with a support leg 2, which plays a supporting role, the lower end of the crushing box 1 is fixed with a discharge hole 11, and the lower end of the crushing box 1 is also provided with a discharge hole 11 connected with a sorting plate 5. The ore to be crushed is put into the crushing box 1 from the upper side, and the crushed ore is discharged from the sorting plate 5.

[0024] In the embodiments of the present application, Figure 2 and Figure 4 Two crushing rollers 3 are arranged inside the crushing box 1, and the ore can be initially crushed by the two crushing rollers 3. A first motor 31 is arranged at the outer end of the crushing box 1, and the output shaft of the first motor 31 is connected to the crushing roller 3. The specific connection method can adopt the existing technology, which can drive one of the crushing rollers 3 to rotate when the first motor 31 is started.

[0025] Furthermore, two transmission blocks 6 are provided on the outer side of the crushing box 1 away from the first motor 31. The transmission blocks 6 are fixed to the crushing roller 3 and are rotatably connected to the crushing box 1. Belts 61 are wound around the outer sides of the two transmission blocks 6, and the belts 61 are in an 8-shape, so that when one group of them is driven to rotate by the first motor 31, it can drive the corresponding transmission block 6 to rotate. When the transmission block 6 rotates, the rotation is transmitted to the other transmission block 6 through the belt 61, and the corresponding crushing roller 3 is driven to rotate through the other transmission block 6, so that the two crushing rollers 3 rotate in opposite directions, and the ore can be initially crushed.

[0026] Further, such as Figure 1 and Figure 2 The inside of the slide plate 4 is provided with a slide plate 4 located below the crushing roller 3, and the slide plate 4 is provided with two slide plates. The inside of the slide plate 4 is provided with a crushing mechanism, and the ore crushed by the crushing roller 3 is crushed for the second time by the crushing mechanism.

[0027] Specifically, the crushing mechanism is composed of an extrusion assembly 8 and a crushing roller 7, and the crushing roller 7 is located on the outside of the extrusion assembly 8, wherein the extrusion assembly 8 is composed of a mounting frame 81, a squeezing roller 82 and a hydraulic telescopic rod 83, the mounting frame 81 is slidably connected to the inside of the slide plate 4, the squeezing roller 82 is arranged on the side of the mounting frame 81 close to the crushing roller 7, and the squeezing roller 82 is rotatably connected to the mounting frame 81, the hydraulic telescopic rod 83 is arranged on the side of the inside of the slide plate 4 away from the squeezing roller 82, the hydraulic telescopic rod 83 is fixed to the crushing roller 3, and the output end of the hydraulic telescopic rod 83 is fixed to the mounting frame 81, and the mounting frame 81 can be started to drive the mounting frame 81 to translate, and the mounting frame 81 can be used to drive the squeezing roller 82 away from or close to the crushing roller 7.

[0028] The crushing roller 7 is rotatably connected to the inside of the crushing box 1. The outer end of the crushing box 1 is provided with a second motor 71 located below the first motor 31. The output shaft of the second motor 71 is connected to the crushing roller 7. The specific connection method can adopt the existing technology. When the second motor 71 is started, the crushing roller 7 can be driven to rotate, and the crushing roller 7 and the squeezing roller 82 are at the same horizontal position, so that the ore can be squeezed and crushed between the crushing roller 7 and the squeezing roller 82.

[0029] Working principle: The staff first puts the ore to be crushed from the top of the crushing box 1, and then starts the first motor 31. At this time, the two crushing rollers 3 rotate towards each other to crush the ore for the first time. The crushed ore falls between the two slides 4. At this time, the second motor 71 is started to drive the crushing roller 7 to rotate, and the ore is crushed for the second time through the extrusion between the extrusion roller 82 and the crushing roller 7.

[0030] At the same time, according to the requirements for the size of the ore crushed, the distance between the squeezing roller 82 and the crushing roller 7 can be adjusted so that the size of the ore after crushing is controlled within the required range. Starting the hydraulic telescopic rod 83 can drive the mounting frame 81 to translate, and the squeezing roller 82 can be moved through the mounting frame 81.
